EFS PRO
Look No Further !! I have dealt with many digestive issues during racing- that usually causes me unable to eat that typically leads to cramping on the bike. Until I found First Endurance, EFS PRO. I am able to get my calories and nutrients without any distress. This is a Must Have for Me. I raced marathon XC Nationals as a Pro, even though I had food in my jersey pockets.- I finished the 4 hour race Strong with only consuming the EFS PRO. I can't say enough about this Mix.. Its just the Best !!

No more Bonking!
Ever since I use EFS Pro for my long training rides, I haven't bonked. For me it's hard to eat during the rides, but the EFS Pro has all the calories and electrolytes I need to make it home feeling strong! I love that they are not very sweet and they don't upset your stomach!
I love EFS Pro!

Further Testing
I have been using EFS-Pro exclusively for 3 years now. During that time I experienced nothing short of amazing results. From cold, rainy, and snowy training to races that had temps in the upper 90's. These were all in Colorado or similar dry western climates however.
During the 2018 season, I traveled to several places with climates that I have only experienced a handful of times in my life such as Arkansas and South Dakota. The humidity and lack of evaporative cooling worried me- especially during the Tatanka Epic in Sturgis, SD. The race started at 85 degrees and the temps ended up climbing into the upper 90's. With EFS-Pro and my other go to First Endurance products I was able to handle this environment when many other people couldn't.

    RIGOROUSLY TESTED IN THE MOST EXTREME CONDITIONS


     

    EFS-PRO delivers higher levels of calories, electrolytes, and other essential nutrients than other drinks without causing GI distress, even in the most extreme conditions. It’s also designed to taste like flavored water so multiple bottles can be consumed easily without the dreaded ‘sweetness fatigue.’ This means EFS-PRO can be mixed at stronger concentrations than other drinks and still be absorbed quickly and easily.

    EFS-PRO utilizes a proprietary “Optimal Absorption Technology” to shuttle water, electrolytes and other essential nutrients through the digestive system more efficiently than ever before, so you don’t have to worry about all the negative symptoms of GI distress. It’s under these extreme racing conditions that it’s critical to have a drink mix that can deliver essential calories, electrolytes, and fluid to working muscles.

    DELIVERS 1400mg OF ELECTROLYTES TO PREVENT CRAMPING & DEHYDRATION


    Clinical research shows endurance athletes require much higher levels of electrolytes than most sports drinks provide in order to prevent cramping and dehydration.

    Each serving of EFS-PRO provides 1400 mg of the essential electrolytes endurance athletes need to stay hydrated and maximize performance.

    WE RECOMMEND TOGETHER


    RESEARCH


    CYCLIC CLUSTER DEXTRIN FOR SUPERIOR ENDURANCE & PERFORMANCE

    EFS-PRO delivers a proprietary blend of carbohydrate sources that each offer unique benefits for endurance athletes. These sources work synergistically to achieve optimal performance through varying channels of absorption. The primary carbohydrate used in EFS-PRO is an amylopectin multi-branched cyclic dextrin that’s 100% soluble in water. It’s a high- glycemic carbohydrate that has little effect on insulin and does not inhibit fat oxidation.

    This means athletes are able to sustain hard efforts through the increased use of fats, which allows them to spare essential glycogen. At 150 mOsm, cyclic dextrin is the low- est-osmolality carbohydrate source available and has been clinically proven to have the fastest gastric emptying time of any carbohydrate. This low-osmolality and superior gastric emptying mean athletes can be assured that what they drink goes directly to working muscles immediately. As a result, EFS-PRO can be mixed at stronger concentrations and still be absorbed properly.

     

    SODIUM CITRATE FOR IMPROVED ABSORPTION

    Sodium citrate is absorbed and metabolized into sodium bicarbonate which creates an alkaline solution that reduces stomach acidity and improves absorption. Alkalizing agents have also been shown to improve performance in high-intensity exercise. Sodium citrate has been clinically shown to have the best absorption rates among vari- ous sodium sources. A clinical study done on Sodium Citrate showed that when it was consumed prior to high-intensity exercise it reduced blood pH and oxygen debt in healthy males exercising on a cycle ergometer.

    L-ALANYL L-GLUTAMINE FOR IMPROVED ABSORPTION

    EFS-PRO contains L-Alanyl L-Glutamine because it’s clinically proven to significantly improve absorption of water and electrolytes in athletes under exercise stress and mild dehydration and improve endurance performance.

    This special dipeptide amino acid is a highly-soluble, water-stable source of glutamine that has a number of unique benefits for endurance athletes. Like L-Glutamine, this dipeptide plays a role in the supply of energy, promotes protein synthesis, heals wounds, pro- motes a healthy intestinal tract and also stimulates immune function.

    The alanine component of L-Alanyl L-Glutamine helps stimulate gluconeogenesis (the generation of glucose through non-carbohydrate sources). Clinical studies on L-Alanyl L-Glutamine have shown it improves plasma glutamine by 26% over standard L-glutamine.

    In a study done in the Journal of the International Society of Sports Nutrition, L-Alanyl L-Glutamine and water were administered to college students with induced dehydration of -2.5% while a second group used only water. The group using L-Alanyl L-Glutamine showed a dramatic improvement in their hydration and serum sodium levels. This group also significantly improved their performance in a treadmill exercise.

    Q&A


    Q: What is EFS-PRO?

    A: EFS-PRO is a new energy drink that provides endurance athletes with the nutrients they need to fuel working muscles and increase endurance during exercise. The EFS formula utilizes the latest clinical research on endurance nutrition and input from some of the best endurance athletes in the world.


    Q: Why doesn’t EFS-PRO contain Vitamin C?

    A: EFS-PRO doesn’t contain Vitamin C because the latest research shows that Vitamin C can have a negative effect on endurance and performance when consumed during exercise. Click here for more info.


    Q: What electrolyte can we find in the new EFS-PRO?

    A: There is 500mg of sodium per serving in the new EFS-PRO drink (EFS has 300mg). This represents the highest sodium content in any electrolyte drink on the market. The EFS-PRO formula now offers over 1,500mg of electrolytes coming from all 5 electrolytes, per serving.

    Furthermore, these superior minerals also offer a buffering of stomach acids. DiCalcium and DiMagnesium malate lower stomach acids significantly helping to reduce the unwanted gastric distress that can be associated with other minerals.


    Q: Are there any changes to the amino acids?

    A: The amino acids in the EFS-PRO drinks are AjiPure amino acids, the purest, most- bioavailable source of free-form amino acids available. AjiPure amino acids have purity levels of 99%-100%. This results in faster and more complete absorption.


    Q: What is the osmolality of the EFS-PRO drink mix?

    A: EFS-PRO has concentration has an osmolality around 250 when mixed at full concentration (32 grams in 12 ounces of water).

    Q: When should I use EFS-PRO instead of EFS?

    A: The link below explains when you should use EFS-PRO instead of EFS and visa versa:

    Q: What is L-Alanyl L-Glutamine? 

    A: The EFS-PRO is also fortified with L-Alanyl L-Glutamine which is a highly soluble water stable source of glutamine with some very unique features. This amino acid has been clinically proven to significantly improve the absorption of water and electrolytes in the intestinal tract.


    Q: What is malic acid used for in the EFS-PRO drinks? Why is this important? 

    A: The new EFS-PRO drink contains 700mg of malic acid. Malic acid stimulates oxygen consumption by increasing mitochondrial uptake, improving mitochondrial respiration and increasing energy production. Malic acid is essential in the formation of ATP, the body’s energy source. Malic acid allows the body to make ATP more efficiently, even under low oxygen, or hypoxic conditions. During anaerobic conditions, malic acid has an ability to remove the accumulation of reducing equivalents. Human studies have shown that after endurance training, athletes’ muscles were characterized by a 50% increase in the malate-aspartate redox shuttle enzymes.


    Q: How is the flavor? 

    A: The new EFS-PRO formula went through extensive flavor testing in the most demanding races in the world. We used this extensive feedback to create a flavor profile that mimics flavored water. With practically no sweetness this formula is ideal for those long, hot workouts where sweet drinks simply do not cut it. All formula uses 100% natural flavors and contains NO color. This allows athletes to use EFS not having to worry about staining water bottles.
